A method for adjusting an operating parameter of an integrated circuit having a memory and logic, where the logic includes a timing circuit, includes accessing the memory, determining a relative speed of the memory access with respect to a speed of the timing circuit, and selectively adjusting the operating parameter based on the relative speed. In one embodiment, an integrated circuit may include a ring oscillator, a shift register having a clock input coupled to an output of the ring oscillator, and compare logic coupled to an output of the shift register. The shift register is enabled in response to initiating a memory access to a memory and disabled in response to completing the memory access. The compare logic provides a relative speed indicator representative of a relative speed of the memory.
